TO ALL WHOM IT MAY CONCERN:

Be it known that I,`OMEIt Hnwns, of the city of Kankakee, inlthe countyrof Kankakee, and State of Illinois, have invented a new and useful modeofconpling cars, entitled Omer Hewess Self-Coupling Gar- Bumper g and Ihereby declare that the following is aifull, clear, andexact descriptionof the construction l and operation ef the same, reference being had tothe annexed drawings,4 makinga part of this specification.`

Same letters refer to like parts.

A'A is a bumper-box or frame, bolted to the under side of a oar; B isthe bumper-head; vC G-are two bars forming the sides of the bumper, andbeing connected with the bumpcrhcad B, and the tie-block K, constitutesthe bumper proper; D is the coupling; E coupling-jaws; F F, steelsprings; G is a vcam for spreading the springs, and disconnectingthccoupling; H is a horizontal shaft to work 'the cam G `I is aperpendicular shaft to work `the cam G; J, a position the`horizon'talshaft H will take to disconnect the coupling. f

Itsjconstruetion consists of the two wrought-iron bars C C, bolted tothe tie-block K, and also to the castiron bumper-head B. It is made towork freely in the casing or box A A., and isprovided with stopsandsprings, V

after the usual manner of holding i'n position, and giving elasticity indrawing. and resisting the shocksgto which it is subjected. The openingin the bumper-head is made of suliieient size to insure the point of thecoupling under all circumstances to enter it. The opening diminishes insize from the front face, so as"to form a bevelsurface with it, as shownVin iig. 2, at b', and serves to guidethc coupling tothecoupling-,jaws'E E. The couplingjaws E E arc made of wrought iron,fastened by a bolt, in a knuckle-joint, inthe angle formed at thebackside of4 the bumper-head and the iron bars 0,0. The bolt'is fittedtight in the jaw, and made to work loosely in the upper anld'lower plateof the bumper-head, so as to admit of its turning freely to and from thecoupling D. To these jaws are attached the steel springs F F, by a boltpassingthrough a slot in the springs, so as to admit of vthe jawsturning in their knuckle-joints. They are firmly screwed to the ironside C C of the bumper, and so constructed astheir elasticity will tendto close theijaws. By this means the coupling D, on enteringthelhumperhead, presses 'apart the jaws until they iiy back behind theprojection in the pyrani'idal point of the coupling,

'and becomes firmly attached to the bumper. The coupling is disconnectedby means of the cam G, which is under control fronteither side of thecar, by thc horizontal shaft H,"and from thc platform or top of the carby the shaft I. The coupling D is forged of wrought iron, tol such shapesubstantially as represented in tigs.13 and 4. The two endsare shaped soas to form a pyramidal head, the offset at the back of which is formedto receive the coupling-jaws.. From thc ends' towards the centre of `thecoupling, the iron is reduced in thickness, by gradually wideningthcsame, so as to form the angles as will conform to the bevel-surfacein the bumperheads, by which means the bumper carrying thc coupling,forces it into the one to be coupled,and also admits of lost motion orslack, the taking up of which enables a trair to get under. headway,when otherwise it would. be unable to start at all. v

-The advantages to bc derived over any invention or coupling now in use,is therapidity in making up a train of cars, or disconnecting the same,without risk or danger to life or limb; also by the peculiar formationof the coupling and the bumper, the diiculty, whereone car stands higherthan another by vmeans of one being 4loaded and the other light, 4isobviated; and also when a car using this bumper'and coupling is run'onton to another road, or in connection with other cars not supplied withthem, the coupling has only to be taken out and the ordinary link andpin inserted.

It will bc seen that the coupling-jaws E operate as levers, and that anystrain or pull upon the coupling D, increases thc force with which saidjaws act upon the shoulders of the coupling, thereby preventing thelatter from being uncoupled until-the jaws are released by the cam.

I claim the 1ever-jaws lh-pivotcd in the angle .between thebumpeehead Band thc side bars C, and attached at their inner ends to the slottedsprings F, in combination with the cam G, whereby the coupling-pin-D is`released frouthe lever-jaws by the action of thc cani upon thc springs,as hereinrshown and described.
